DIE FOR CUTTING AND ORNAMENTING LEATHER.

SPECIFICATION forming part of Letters Patent No. 642,878, dated February6, 1900.

Application filed March 14, 1898. Serial No. 673,723- (ModeL) To to whomit may concern.-

Be it known that I, JOHN G. SCHNEIDER, of Boston, in the county ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in Dies for Cutting and Ornamenting Leather, of which thefollowing is a specification.

This invention relates to devices for cutting and ornamenting leather;and it has for to its object to provide improvements in the meanswhereby the operations of cutting and ornamentally creasing the leathermay be simultaneously performed, the particular object usually being tomake a cut or slit in the I 5 leather and alongside of and parallel withsaid slit a crease which gives the leather the appearance of beingfolded over and sewed at the edge of the slit.

The invention consists in the novel fea- 2o tures of construction andarrangement,which I shall now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a reverse plan view of a die constructed inaccordance with my invention. Fig. 2 represents a top plan view thereof.Fig. 3 represents a front elevation. Fig. 4. represents a verticalsection through the die and work, showing also a method of mounting thetwo 0 in their operative relation to each other. Fig.

5 represents a perspective view of the finished work with one edge ofits slit depressed to open the slit. Fig. 6 represents a perspectiveView of an apparatus in which the die is 5 used, showing the die inplace and the templet supporting the same opened away from theunderlying plate.

The same reference characters indicate the same parts in all thefigures.

Referring to the drawings, (t designates the die-body, consisting,preferably, of a plate or block of metal.

I) designates a knife secured to the front edge of the plate aby meansof screws 0 c, 5 which occupy slots b b in the knife, the knife beingthereby rendered vertically adjustable on the plate. Behind the edge ofthe knife Z) and rigidly secured to theplate a is a blade or bead (1,having a blunt lower edge arranged parallel to the edge of the knife I),the lower edge of the knife extending somewhat below that of the blade.

at d are blades similar to the blade (I, attached to the plate a andextending in suitable directions, so as to form an ornamental creasedpattern when applied to theleather.

The die may be used in various ways. In Figs. 4 and 6 I have shown anapparatus in which the die is employed to cut and ornament blanks forleather pocket-books. said apparatus consists of two plates h and t',hinged at t" and arranged to open and shut like the covers of a book.The lower plate h has a recess h corresponding to the shape of theblank, and the upper plate has recesses or perforations t through whichthe knife b and blades d d of the die extend. When a piece of leather isto be operated on, the ap paratus is placed upon a bed or block 6 ofwood or other suitable material which will not injure the knife. Theblank f is then placed in the guide or recess h and the operatin gportions of the die are passed through the perforations in the lowerplate or templet 2', so as to be brought in contact with the uppersurface of the leather when the plates are closed together. Theapparatus may then be placed in a press, which presses the die againstthe leather, causing the knife to pass through the same and form a slit,while the blade at operates to form a crease alongside of and parallelto said slit and the blades d form an ornamental crease on another partof the leather, or the die-plate may be struck with a mallet to forcethe die against the leather, or any other suitable means might beemployed to press the die against the leather and cause it to operate,as described. With the apparatus shown in Figs. 4. and 6 the work can berapidly and accurately per- 0 formed. The die and the leather blankalways have the same position relative to one another when broughttogether, and the slit and creases are therefore uniformly placed ondifferent blanks.

Fig. 5 shows apocket-book piece produced by the die shown in theprevious figures, the lower right-hand margin of the piece beingrepresented as depressed to separate the edges of the slit. It isobvious that any suitable 10o The 60 conformation may be given to theedges of the knife or knives employed in my improved die and thecreasing-blades cooperating therewith. The die may be so constructed andarranged that instead of forming one or more slits in the leather blankwith creases parallel thereto itsevers a portion of material from theblank and forms a terminal creased edge on said blank.

The creasing-blades cl and d are formed from elongated strips of pliablemetal, preferably brass, which strips are bent to the desiredconformation and are affixed to the dieplate a by inserting them ingrooves or recesses formed in the lower face of said plate, with theirlower edges projecting below the plate, as shown, solder or othersuitable fiX- ing means being preferably employed to secure said stripsin place.

I am aware that itis not new to construct a die with creasing andcutting portions side by side which operate simultaneously on theleather; but it has been the practice heretofore, so far as I amaware,to construct such dies with the creasing ridges or beadsintegrally formed on the face of the die-plate. This necessitates thecareful removal of the metal around the ridges in order to finish themproperl y, acomparatively expensive and tedious process compared withthe method of forming the die above described, since by the said methodthe grooves can be more or less roughly formed in the plain face of thedie, following the desired course of the creases, and thecreasing-blades,which can be finished with great facility in the form ofstrips, can then be quickly bent to shape and inserted in the die-plate.

I claim 1. Adie forcuttingand ornamenting leather comprising a die-plategrooved or recessed on its face, one or more creasing-blades consistingof metal strips fixed in said grooves or recesses and having blunt loweredges projecting beyond the face of the die-plate and a cut-- ting-blade or knife attached to the die in proximity to saidcreasing-blades, whereby the die acts to simultaneously out and creasethe leather.

2. An apparatus of the characterdescribed, comprising a plate formedwith a guide adapted to receive a leather blank, and a second platehinged to the first plate and carryinga die adapted to simultaneouslycutand crease the leather blank, substantially as described.

In testimony whereof I have affixed my signature in presence of twowitnesses.

JOHN G. SCHNEIDER.
